In order to meet the demands of developers for launching on various platforms and truly achieve development in one place and running everywhere, 1.4 version began to support multi-platform export. Projects created by developers through the editor can be quickly exported to the projects required by different platforms.

## Prepare in Advance
After the project is developed in the editor, you can export the project for each platform and publish it. Before exporting, let's first understand the export panel and export settings.

### Export Panel
When we complete the project development and need to export it to a certain platform (taking exporting to the WechatMiniGame platform as an example), we can follow the steps below:

1、Click the Export button on the left side of the editor:

2、On the left side of the export panel that appears, select the export platform:

3、On the right side of the export panel are some project-related export configurations, which are mainly divided into two parts: **General configuration** (in the red box) and **Platform-related configuration** (in the yellow box):

### Export Configuration Instructions

The platform-related export configuration will be described separately in the platform export document. Here we focus on the **general configuration** that is independent of the platform.

| Configuration          | Describe                                                                                                                              |
